Given Input Data is 781, 847, 44, 559

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 781 is 11 x 71

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 44 is 2 x 2 x 11

Prime Factorization of 559 is 13 x 43

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(781, 847) = 60137

GCD(781, 847) = ( 781 x 847 ) / 60137

GCD(781, 847) = 661507 / 60137

GCD(781, 847) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 44

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(11, 44) = 44

GCD(11, 44) = ( 11 x 44 ) / 44

GCD(11, 44) = 484 / 44

GCD(11, 44) = 11

Step3:

Here we consider the GCD from the above i.e. 11 as first number and the next as 559

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(11, 559) = 6149

GCD(11, 559) = ( 11 x 559 ) / 6149

GCD(11, 559) = 6149 / 6149

GCD(11, 559) = 1

GCD of 781, 847, 44, 559 is 1
